Untrusted JS

A Javascript puzzle in which you hack your way out.  Brilliant.

http://alexnisnevich.github.io/untrusted/

Untrusted is created by Alex Nisnevich and Greg Shuflin.  I’ve made my own solutions below:

Level 01 Cell Block A

      for (x = 5; x <= map.getWidth() - 5; x++) {
        map.placeObject(x, 3, 'block');
        map.placeObject(x, map.getHeight() - 10, 'block');
    }

Level 02 The Long Way Out

Simply comment out the code:

/* then */

Level 03 Validation Engaged

Just move a wall:

    for (y = 10; y <= map.getHeight() - 3; y++) {
        map.placeObject(5, y, 'block');
        map.placeObject(map.getWidth() - 10, y, 'block');
    }

    for (x = 5; x <= map.getWidth() - 5; x++) {
        map.placeObject(x, 10, 'block');
        map.placeObject(x, map.getHeight() - 3, 'block');
    }

Level 04 Multiplicity

Add a new exit somewhere handy:

    map.placeObject(10, 15, 'exit');

Level 05 Minesweeper

Highlight the mines

    map.setSquareColor(x,y, '#fff');

Level 06 Drones 101

Block the drone anywhere

    map.placeObject(10, 10, 'block');

Level 07 Colors

Toggle the player color with the phone

            var player = map.getPlayer();
        if (player.getColor() == '#0f0') {
          player.setColor('#f00');
        } else if (player.getColor() == '#f00') {
          player.setColor('#ff0');
        } else {
          player.setColor('#0f0');
        }

Level 08 Into The Woods

Regenerate forest as you move towards the exit:

    generateForest

Level 09 Fording the River

Use your phone to toggle raft direction

    map.getPlayer().setPhoneCallback( function() {
if (raftDirection == 'up') {
  raftDirection = 'down';
  } else {
    raftDirection = 'up';
  }
});

Level 10 Drone Ambush

Attack drones behaviour:

    if (me.getY() == 13) {me.move('left')} else {me.move('down')};

Reinforcement drones behaviour:

    // nothing

Defence drones behaviour:

    if (me.getY() == 13) {me.move('right')} else {me.move('down')};

Level 11 Robot

Get the robot to move

    if (me.canMove('right'))
  me.move('right');
else
  me.move('down');

Level 12 Robot Nav

use the phone to change direction of the robot at will

                if (dir == 0) {
                me.move('up');
            } else if (dir == 1) {
                me.move('right');
            } else if (dir == 2) {
                me.move('down');
            } else if (dir == 3) {
                me.move('left');
            }
        }
    });

    var dir = 0;
    map.getPlayer().setPhoneCallback(function () {
      if (dir == 0) {
        dir = 1;
      } else if (dir == 1) {
        dir = 2;
      } else if (dir == 2) {
        dir = 3;
      } else {
        dir = 0;
      }
    });
    map.defineObject('defencedrone', {
        'type': 'dynamic',
        'symbol': 'D',
        'color': 'gray',
        'onCollision': function (player, me) {
            me.giveItemTo(player, 'greenKey');
        },
        'behavior': function (me) {

Level 13 Robot Maze

Same as before, use the phone to change direction

                if (dir == 0) {
                me.move('up');
            } else if (dir == 1) {
                me.move('right');
            } else if (dir == 2) {
                me.move('down');
            } else if (dir == 3) {
                me.move('left');
            }
        }
    });

    var dir = 0;
    map.getPlayer().setPhoneCallback(function () {
      if (dir == 0) {
        dir = 1;
      } else if (dir == 1) {
        dir = 2;
      } else if (dir == 2) {
        dir = 3;
      } else {
        dir = 0;

Level 14 Crisps Contest

Why not add a new key while we’re about it?

    'greenKey');map.placeObject(25,10,'greenKey'

Level 15 Exceptional Crossing

Use an undefined variable

    boom

Level 16 Lasers

Add a new exit somewhere handy:

            // using canvas to draw the line
        var ctx = map.getCanvasContext();
        ctx.beginPath();
        ctx.strokeStyle = color;
        ctx.lineWidth = 5;
        ctx.moveTo(x1, y1);
        ctx.lineTo(x2, y2);
        ctx.stroke();

And then use the phone to toggle player color:

    player.setPhoneCallback(changeColor);
function changeColor() {
  if (player.getColor()==='red')
    player.setColor('teal');
  else if (player.getColor()==='teal')
    player.setColor('yellow');
  else
    player.setColor('red');
}

Level 17 Pointers

Ha! this was easy – simply rewrite the portals so that the first portal always takes you to the exit:

            var easy = map.getDynamicObjects();
        t1 = easy[0];
        t2 = easy [167];
        t1.setTarget(t2);
        t2.setTarget(t1);

Level 18 Super Dr Eval Bros

Create a ladder with your phone

      var player = map.getPlayer();
  map.placeObject(player.getX()+1, player.getY()+1, 'ladder');
}
map.defineObject('ladder',{
  'type': 'static',
  'symbol': '=',
  'impassable': true,
  'color': 'brown',});
function empty(){

Level 19 Document Object Madness

Use the arrow keys to get both red and green player symbols in the same element.

Level 20 Boss Fight

Not my code, kudos to DaFrElUf – block the bullets, get the phone and blast the boss.

    map.defineObject('wall',{
  'type': 'static',
  'symbol': '~',
  'impassable': true,
  'color': 'white',});
map.defineObject('gun',{
  'type': 'static',
  'symbol': '>',
  'impassable': true,
  'color': 'white',});
for	(var x = 1; x < 49; x++){
	map.placeObject(x, 9, 'wall');
}
for (var y = 5; y < 7; y++){
	map.placeObject(0, y, 'gun');
}
map.defineObject('bullet2', {
  'type': 'dynamic',
  'symbol': '-',
  'color': 'red',
  'interval': 100,
  'projectile': true,
  'behavior': function (me) {me.move('right');}
});
function shoot() {
var player = map.getPlayer();
map.placeObject(1, 5, 'bullet2');
map.placeObject(1, 6, 'bullet2');
}
map.getPlayer().setPhoneCallback(shoot);

Level 21 End of the Line

Go to Menu > Scripts > objects.js and replace this code:

                    if (!game.map.finalLevel) {
                    game._callUnexposedMethod(function () {
                        game._moveToNextLevel();
                    });
                }

With this:

                    
                        game._moveToNextLevel();
